A low VOC, two component internally flexibilised high build surface tolerant epoxy primer. Pigmented with aluminium and lamellar micaceous iron oxide for improved corrosion resistance. This formulation represents second generation surface tolerant technology. The product has both application and performance characteristics optimised for use over a wider temperature range.

PRODUCT DESCRIPTION

A high performance industrial maintenance coating for use on a wide variety of surfaces including hand or power tool cleaned rusty steel. Interplus 256 is particularly useful in the maintenance of offshore structures and other aggressive environments such as oil refineries, coastal structures, pulp and paper mills and bridges where dry abrasive blasting is not possible. Ideal for use in conjunction with wet abrasive blasting or ultra high pressure water blasting, or as a patch primer for rusty surfaces in maintenance situations. For use on hot surfaces continuously running at up to 150C (302F) and for corrosion protection under thermal insulation of carbon steel and stainless steel.

Interplus 256Surface Tolerant Epoxy

The performance of this product will depend upon the degree of surface preparation. The surface to be coated must be clean and free from contamination. Prior to paint application all surfaces should be assessed and treated in accordance with ISO 8504:2000. Accumulated dirt and soluble salts must be removed. Dry bristle brushing will normally be adequate for accumulated dirt. Soluble salts should be removed by fresh water washing. Abrasive Blast Cleaning Interplus 256 may be applied to a surface abrasive blast cleaned to a minimum Sa1 (ISO 8501-1:2007) C or D grade rusting, or SSPC SP7. Hand or Power Tool Preparation Hand or power tool clean to a minimum of St2 (ISO 8501-1:2007) or SSPC-SP2. Note, all scale must be removed and areas which cannot be prepared adequately by chipping or needle gun should be spot blasted to a minimum standard of Sa2 (ISO 8501-1:2007) or SSPC-SP6. Typically this would apply to C or D grade rusting in this standard. On hot steel surfaces, cleaning to a minimum St3 (ISO 8501-1:2007) or SSPC SP3 is required. Optimum performance will be achieved from SPPC-SP11 for hand preparation, or blasting to Sa2 (ISO 8501-1:2007) or SSPC-SP6. Ultra High Pressure Hydroblasting / Abrasive Wet Blasting May be applied to surfaces prepared to Sa2 (ISO 8501-1:2007) or SSPC-SP6 which have flash rusted to no worse than Grade HB2M (refer to International Hydroblasting Standards). It is also possible to apply to damp surfaces in some circumstances. Further information is available from International Protective Coatings. Aged Coatings Interplus 256 is suitable for overlap onto most aged coating systems. Loose or flaking coatings should be removed back to a firm edge. Glossy epoxies and polyurethanes may require abrasion.

SURFACE PREPARATION

Material is supplied in two containers as a unit. Always mix a complete unit in the proportions supplied. Once the unit has been mixed it must be used within the working pot life specified.(1) Agitate Base (Part A) with a power agitator.(2) Combine entire contents of Curing Agent (Part B) with Base

(Part A) and mix thoroughly with power agitator.

3.0 part(s) : 1.0 part(s) by volume

Recommended Typically 75-125 microns (3.0-5.0 mils) can be achieved

Recommended Typically 75-100 microns (3.0-4.0 mils) can be achieved

International GTA220

International GTA822 or International GTA415

Do not allow material to remain in hoses, gun or spray equipment. Thoroughly flush all equipment with International GTA822. Once units of paint have been mixed they should not be resealed and it is advised that after prolonged stoppages work recommences with freshly mixed units.

Clean all equipment immediately after use with International GTA822. It is good working practice to periodically flush out spray equipment during the course of the working day. Frequency of cleaning will depend upon amount sprayed, temperature and elapsed time, including any delays. All surplus materials and empty containers should be disposed of in accordance with appropriate regional regulations/legislation.

Do not thin more than allowed by local environmental legislation

Interplus 256Surface Tolerant Epoxy

Interplus 256 is the preferred product for application to hand prepared rusty steel, and is particularly suitable as a patch primer. In these circumstances, application should be performed by brush to ensure good wetting of the hand prepared substrate. For larger areas which have been prepared by power tool cleaning, or brush blast, other products may be suitable. Please consult International Protective Coatings for details.

In order to ensure good anti-corrosive performance, it is important to achieve a minimum system dry film thickness of 200 microns (8 mils) by application of multi-coats over hand prepared steel.

When applying Interplus 256 by brush, it may be necessary to apply multiple coats to achieve the total specified system dry film thickness.

To ensure good aged overcoating of Interplus 256 by other materials the surface must be clean, dry and free from contamination, particularly if the surface profile is rough due to the presence of micaceous iron oxide.

Application and curing at temperatures below 10C (50F) will result in significantly prolonged curing times, and in these circumstances it is recommended that Interplus 356 should be used.

Interplus 256 can be applied to substrates with surface temperatures at time of application up to 100C (212F). In these circumstances, rapid application of multiple coats is necessary to achieve the correct film thickness, and suitable personal protection equipment is essential during application due to the rapid release of volatiles from the applied film. Refer to Interplus 256 Recommended Working Procedures.

Interplus 256 is suitable for protection of steel operating at continuous dry temperatures of up to 150C (302F), with intermittent surges up to 200C (392F).

Interplus 256 is not designed for continuous water immersion.

Elevated Temperature Curing

An alternative curing agent is available for applications at temperatures greater than 25C (77F).
